A San Francisco getaway for less than $75 a person? Yes, you can do it. How do I know?

Because I recently made such a trip by using the uber-cheap Megabus service from Los Angeles and snapping up food and museum deals. The total tab for my 17 hours in the city, including round-trip transportation there, was $71.37.

Here’s how I spent so little to visit what TripAdvisor recently ranked as the fourth most expensive major tourist city in America.
